The dumbell chart

A wedding gown entails multilayering of expensive specialty fabrics for an outfit
whose useful lifespan may come and go in a single afternoon…
— Mary Roach

Millions of weddings take place every month, and couples across the world find themselves with more and more choices for when, where and how to celebrate their love. The Knot, WeddingWire and Bodas.net teamed up to gather feedback from 20,000 couples in 14 countries to understand how today’s couples are planning their wedding. Let’s explore using a dumbbell chart to illustrate some of the findings.

Ingest

country, vendor, percent

url_root <- "https://raw.githubusercontent.com/UN-AVT/kamino-source/main/sources/0-shared/data/"
url_file <- "expensive-weddings/expensive-weddings.csv"
url <- paste0(url_root, url_file)

df <- read.csv(url, header = TRUE, stringsAsFactors = FALSE,  encoding = "UTF-8")
df

# to make emoji map
# unique(df$Vendor)

Wrangle

enrich with emoji map

Analyze

summarize for min and max (to use as segment points)

df_wo_alcohol <- filter(df, Vendor != "Serve alcohol")

df_segment <- df_wo_alcohol %>%
  dplyr::select(Country, Percent) %>%
  group_by(Country) %>%
  summarise(
    min_pt = min(Percent, na.rm = T),
    max_pt = max(Percent, na.rm = T)
)
